On solution to steady Total Least Squares of two-dimensional coordinate conversion

从经典的总体最小二乘方法出发,以二维平面坐标转换为例,展示了稳健总体最小二乘方法的解算过程。通过实验数据证明了采用稳健总体最小二乘方法计算,能够较好地达到粗差定位的目的,且最终得到准确的、更为合理的解。

From the classical Total Least Squares, the study displays the solution process for steady Total Least Squares by taking the two-dimen- sional coordinate conversion as the example, and proves the calculation with the steady Total Least Squares can realize the gross error location in a better way and concludes the accurate and reasonable solution according to the experimental data.
